Documenting and validating complex JSON Schemas can be hard. This tool makes it easier by providing a number of scripts that can turn JSON Schema files into readable Markdown documentation that is ready for consumption on GitHub or processed using Jekyll or other static site generators.
These tools have been introduced by Adobe to document Adobe's Experience Data Models (XDM), but can be used for other JSON Schema documents, too.
jsonschema2md
is developed against JSON Schema 2019-09
, but not the full vocabulary is supported. Please check the detailed list of JSON Schema keywords supported by jsonschema2md
. This list is updated by our tests.
npm
version 3.10.8 or upnode
v18 or v20 or up
Using the schemas in examples/schemas
(note the *.schema.json
extension), the output in examples/docs
has been generated.
$ npm install -g @adobe/jsonschema2md
# show usage information
$ jsonschema2md
# run task
$ jsonschema2md -d examples/schemas -o examples/docs
# generated output for whole folder is written to ./examples/docs
By default, jsonschema2md
looks for schema files ending in *.schema.json
. You can specify another extension by using the --schema-extension
or -e
command line argument.
The generated documentation can be internationalized. Select the language you want to use for the output using the -l
parameter.
Supported languages are:
- English
- German

jsonschema2md
displays only the attributes of an property which are defined by the JSON Schema standard. If you want to display additional attributes in the property description you could provide these with the --properties
(or -p
) parameter.
# include both the `version` and the `test` attribute
$ jsonschema2md -d examples/schemas -o examples/docs -p version -p test
In some cases you do not need a header because it does not provide any useful information. With the --header
(or -h
) parameter you can disable the inclusion of headers.
# run against JSON Schema Draft 06
$ jsonschema2md -d examples/schemas -o examples/docs -v 06 -h false
If you are using JSON Schema to validate YAML documents, for instance configuration files, you might wish for examples to be formatted as YAML, not JSON. Using the command line option -f yaml
or --example-format yaml
achieves this goal.
You can conveniently use the JSON Schema Markdown Tools from npm
. This makes it possible to set up a conversion toolchain for your JSON Schema project that is driven entirely by npm
. To do so, first define the dependency by adding this to your "devDependencies"
section of package.json
"devDependencies": {
"@adobe/jsonschema2md": "^6.0.0"
}
Then add the following to the "scripts"
section of your package.json
and adapt accordingly:
"scripts": {
"prepare": "mkdir -p docs/reference && jsonschema2md -o docs/reference -d schemas/draft-04"
}
If you run npm install
before running npm run prepare
, npm
will install the @adobe/jsonschema2md
in a node_modules/.bin
path, even if you did not install the JSON Schema Markdown beforehand.
const {jsonschema2md} = require('@adobe/jsonschema2md');
const schema = require('examples/schemas/example.schema.json');
const markdown = jsonschema2md(schema, {
includeReadme: true,
});
Ensure you have all the dependencies installed via npm install
, then run:
npm test
This will run our Jasmine test suite as well as lint the JavaScript according to our style guide (see below).
Continuous integration runs on Github Actions.
All pull requests automatically trigger a job that runs the tests by executing the main.yml
.
npm run test
will generate a code coverage report at the end of the test run. Anything below 100% coverage counts as a test failure.
This project uses eslint to enforce JavaScript coding style. To run the linter:
npm run lint
